A wheel 2.00 m in diameter lies in a vertical plane and rotates with a constant angular acceleration of 4.00 rad/s2. The wheel starts at rest at t = 0, and the radius vector of a certain point P on the rim makes an angle of 57.3° with the horizontal at this time. At t = 2.00 s, find
(a) The angular speed of the wheel,
(b) The tangential speed and the total acceleration of the point P, and
(c) The angular position of the point P.
